I was using NIS 2009 received a notification I could update to NIS 2010. I did. Everything worked fine except when I went to do a system scan. My system would reach a certain point in the scanning process it would lock up and go to a blank screen. I had to reboot each time. Tried several time's did the same thing each time. Finally uninstalled the update and reinstalled a older version of NIS and it seems to working good..I'm reluctant to say the least to upgrade to the new one..Is there a fix for this problem?
